I was a big fan of their first two CDs ("Shake Your Money Maker" and "Southern Harmony...."). They kinda lost me with "Threes Snakes and one Charm". After those, I haven't heard anything other then the "By Your Side" CD.
They took a long hiatus after that album and came back with "Warpaint" - I think it's excellent, it sold very well, and for what it's worth the critics liked it to (I just know what I enjoy).
This Acoustic CD that you speak of,,,, would that be the VH1 Unplugged? I may go and acquire this.[/QUOTE]
It's called Croweology....more or less of a greatest hits celebrating 20 years but they do it acoustically and different, so t might be worth looking into.
Another GREAT one IMO is "Brothers of a Feather" - actually not a Black Crowes album but Chris and Rich Robinson only, doing some of their favorite covers, a few BC tunes, and some original stuff.....this is one of my favorite albums of all time and I definitely recommend it is worth looking into.
